ISO 834-11:2014中详述的评估旨在涵盖防火材料的一系列厚度、以截面系数为特征的一系列型钢、一系列设计温度和一系列有效耐火等级。 ISO 834-11:2014涵盖了消防系统，包括本文件中定义的被动材料（板、垫、板和喷涂材料）和反应材料。 评估程序用于确定:a）基于加载和卸载试样测试得出的温度数据，消防系统（物理性能）使用的修正系数和实际限制，以及b）基于卸载短钢试样测试得出的温度数据，防火材料的热性能（热性能）。 定义了评估结果的适用范围，并允许将结果直接应用于不同的钢截面尺寸和强度等级（但不包括不锈钢）以及测试的消防系统。根据ISO 834？10获得的试验结果和ISO 834本部分中的评估直接适用于“I”和“H”横截面形状的钢型材和空心型材。I型或H型截面的分析结果直接适用于具有相同截面系数的角钢、槽钢和T型截面，无论是用作单个构件还是作为装配式钢桁架的一部分。 评估结果适用于预制截面。 ISO 834-11:2014不适用于包含任何类型或实心钢筋的孔或开口的混凝土填充空心型材、梁或柱。

The assessment detailed in ISO 834-11:2014 is designed to cover a range of thicknesses of the fire protection material, a range of steel sections characterized by their section factors, a range of design temperatures, and a range of valid fire resistance classification periods. ISO 834-11:2014 covers fire protection systems that include both passive (boards, mats, slabs, and spray materials) and reactive materials as defined in this document. The assessment procedure is used to establish: a) on the basis of the temperature data derived from testing loaded and unloaded specimens, a correction factor and practical constraints on the use of the fire protection system (the physical performance), and b) on the basis of the temperature data derived from testing unloaded short steel specimens, the thermal properties of the fire protection material (the thermal performance). The limits of applicability of the results of the assessment are defined together with permitted direct application of the results to different steel section sizes and strength grades (but not stainless steels) and to the fire protection system tested. The results of the tests obtained according to ISO 834？10 and the assessment in this part of ISO 834 are directly applicable to steel sections of "I" and "H" cross-sectional shape and hollow sections. Results from analysis of I or H sections are directly applicable to angles, channels, and T-sections for the same section factor, whether used as individual elements or as part of a fabricated steel truss. The results of the assessment are applicable to fabricated sections. ISO 834-11:2014 does not apply to concrete-filled hollow sections, beams, or columns containing holes or openings of any type or solid bar.
